Which radio is this? (HPSDR Hermes)
The Quicksilver does 8 receive channels now in the FPGA.
It's just a matter of gate real estate. There is the question of
how to get from the QS-1E exciter board up to power that
qualifies as QRP instead of the QQQQRP output level of
the barefoot board. Several folks that have the exciters are
working that problem. The good part is that the QS-1R with
the QS-1E "factory installed" is about $1200 all-in (if i remember
correctly - not off by too much if wrong). Then the xmit PA
chain can be added incrementally. the Phil's software already
supports the TX functions.
it's actually pretty interesting to compare the F-6X00 with
the Quicksilver. There will certainly be some back-and-forth
about who did what first, but by my read, the QS did multiple
receive channels first (that's been working for quite a while
and the interfaced with the web server so multiple remote
users can look at multiple bands - i believe the multiple
channels was first hacked into the Verilog by a user!),
Phil has had the CW keyer with direct sidetone and waveform
synthesis all in the FPGA since the very first protos of the exciter.
Here we have a classic example of "leap-frogging". each successive
product can move the bar significantly because of the newest
parts they get to design with. Sometimes the competitor that
starts 6 months *after* the first-mover has a significant advantage
precisely because he could design with better/faster/denser/cheaper
parts than when the first-mover had to freeze the design. They may
even hit the market at almost the same time in spite of a large
difference in elapsed calendar and total cash burned. This is why
being too early to a market is easily just as fatal as being late.
The new FPGAs are an interesting point of comparison viz this issue.
I believe the QS uses the FPGA it does because it's the biggest part
he could get (at the time) that was leaded - everything denser used
Ball Grid Array. I suspect that decision was driven by the hopes
of offering the QS as a kit, not to mention the expense of building and
debugging BGA prototypes on a shoestring budget.
(BGA debug daughters are available but are not cheap and require a seriously
expensive socket on the prototype board and still precludes a lot of
"blue-wire"
and "dead-bug" hacks as seen in most protos.) as the QS is now
line-assembled
and given the engineering experience if Phil did it again today (QS-2???),
i suspect the BGA issue might not loom as large as it did then
Radio History question:
i have seen references suggesting that the arrival
of the Collins rigs with out-of-the-box SSB support (and the adoption by
SAC!) might represent the tipping point where SSB transitioned from
the darling of the hard-core hackers to mainstream, as in you didn't have
to build something to run sideband.
IS THIS TRUE? What was the first generally-available rig that came out
of the box with solid SSB support?
my point is whether the FLEX 6x00 radios is a parallel to, eg, Collins,
that SDR has arrived at the tipping point. Clearly Very Not Cheap, but
now clearly packagable as an "appliance" and not an exercise in
technology exploitation for the industrious.
